An Extinction Rebellion activist is walking 300 kilometres from Sydney to Canberra along the Motorway in order to disrupt traffic along the major travel route. 

The protest march began on April 2, with participants hitting the 160 kilometre mark over the weekend. A 21-year-old participant was arrested on the Hume Motorway south of Campbelltown, charged with failure to obey police when asked to leave the Motorway.

The activist group is attempting to highlight the need for urgent and drastic climate action and a transition to net zero emissions by 2025.
